nPerf offers an Internet speed test application, which can be used for free at http://www.nPerf.com.

The results obtained are subject to automatic and manual checks to avoid duplication and to rule out possible abusive or fraudulent use (massive tests, robots ...).

To ensure maximum user bandwidth at all times, nPerf relies on a network of servers dedicated to this task. These servers are located with hosts in Switzerland and abroad. Switzerland providers are welcome to install nPerf servers, that’s free!"
